BMC Research Notes, 2020 Objective As human thermoregulatory responses to maintain core body temperature (Tcore) under multiple stressors such as cold, hypoxia, and dehydration (e.g., exposure to high-altitude) are varied, the combined effects of cold, hypoxia, and dehydration ...

mSystems, 2020 Methylobacter species, members of the Methylococcales, have recently emerged as some of the globally widespread, cosmopolitan species that play a key role in the environmental consumption of methane across gradients of dioxygen tensions. In this work, we

The hypoxic transcription factor KlMga2 mediates the response to oxidative stress and influences longevity in the yeast Kluyveromyces lactis [PDF]
, 2019 Hypoxia is defined as the decline of oxygen availability, depending on environmental supply and cellular consumption rate. The decrease in O2 results in reduction of available energy in facultative aerobes.

Frontiers in Physiology, 2021 Developmental plasticity can elicit phenotypic adjustments that help organisms cope with environmental change, but the relationship between developmental plasticity and plasticity in adult life (e.g., acclimation) remains unresolved. We sought to examine

The steroid hormone ecdysone regulates growth rate in response to oxygen availability
Scientific Reports, 2022 In almost all animals, physiologically low oxygen (hypoxia) during development slows growth and reduces adult body size. The developmental mechanisms that determine growth under hypoxic conditions are, however, poorly understood.

Effects of hypoxia on benthic macrofauna and bioturbation in the Estuary and Gulf of St. Lawrence, Canada [PDF]
, 2010 The bottom water in the 4300 m deep Lower St. Lawrence Estuary (LSLE) is persistently hypoxic in contrast to the normoxic bottom waters in the Gulf of St. Lawrence (GSL). We photographed the seabed at 11 stations in the Estuary and Gulf of St.

Hypoxia: The “Invisible Pusher” of Gut Microbiota
Frontiers in Microbiology, 2021 Oxygen is important to the human body. Cell survival and operations depend on oxygen. When the body becomes hypoxic, it affects the organs, tissues and cells and can cause irreversible damage.

The Influence of Body Size and Hemoglobin Multiplicity on Critical Oxygen Threshold in Red Drum (Sciaenops ocellatus) [PDF]
, 2016 Hypoxia is common in marine environments and fishes use a suite of cardiorespiratory adjustments to defend aerobic metabolism, including reducing standard metabolic rate (SMR), the minimum metabolic rate needed to sustain life at a specified temperature,

Hypoxia and Brain Aging: Neurodegeneration or Neuroprotection?
Ageing Research Reviews, 2021 The absolute reliance of the mammalian brain on oxygen to generate ATP renders it acutely vulnerable to hypoxia, whether at high altitude or in clinical settings of anemia or pulmonary disease.

An Inexpensive Open-Source Chamber for Controlled Hypoxia/Hyperoxia Exposure
Frontiers in Physiology, 2022 Understanding hypoxia/hyperoxia exposure requires either a high-altitude research facility or a chamber in which gas concentrations are precisely and reproducibly controlled.
